To all whom t may concern:

Be it known that 1, WILLIAM J. NEsBIT'r, a citizen of the United Statesof America, residing at Los Angeles, county of Los Angeles, State ofCalifornia, have invented a certain new and useful Heel-CuttingApparat-us; and I do hereby declare the following to be a full, clear,and eXact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to improvements in heel cutting apparatus; and itmay be said to consist in the provision of the novel and advantageousfeatures and in the novel and improved construction, arrangement, andcombination of parts as will appear from the description and claimswhich follow hereinafter.

One object of the invention is to provide a novel and improvedconstruction whereby the heel holding device is adjustable relatively tothe cutting device.

Another object of the invention is to provide a novel and improved heelholding device.

A further object of the invention is to provide a novel and improvedheel-cutting device.

A further object of the invention is to provide a` novel and improvedheel cutting apparatus which is simple and compact in design, economicalto manufacture, install, and operate, practical and convenient to use,and generally effective for its purpose.

Other objects and the advantages of the invention will be apparent tothose skilled in the art from a careful consideration of the followingdescription ofthe preferred construction embodying the invention, takenin connection with the accompanying drawings in which Figure 1 is a sideelevational View of the heel cutting apparatus; Fig. 2 is a plan view ofthe same; Fig. 3 is a plan view of the frame; Fig. 4 is a sectional viewtaken on the line 4--4 of Fig. 1; Fig. 5 is 'side elevational view ofthe heel cuttingv device; Fig. 6 is a front elevational view of thesame; Fig. 7 is an enlarged sectional view taken on the line 7 7 of Fig.5; Fig. 8 is an enlarged broken sectional view showing the heel cuttingdevice and a partly cut heel; Fig. 9 shows plan and elevational viewsofthe arm which carries the shoe holding device; and

Fig. 10 shows elevational and plan views of a part of the heel holdingdevice.

The frame 11 has on its underside a suitable stem 12 whereby it can bereadily attached to a suitable pedestal 13 which is partly indicated bydotted lines in Fig. 1. Said frame 11 has at its'forward end thebearings 14 and 15, and it has at its rear end the upright extension 16and the toothed part 17. i

A bifurcated-lever 18 is provided with the bearings 19 and 20; and saidlever has at its upper end the handle 21, and it has at its lower endthe pivots 22 and 23 which are litted in the bearings 14 and 15.

The heel cutting device consists of the circular saw 24 and the thrustfinger 25 which are both mounted on the lever 18. The circular saw 24 istted on the squared portionA 26 of the shaft 27 which latter has fastthereon the sprocket pinion 28 and is fitted in the 'bearing 19. Areduced portion 29 of the shaft 27 has thereon the sleeve 30 which isfitted in the bearing 20 and jammed against the circular saw 24 by thelock nut V31. Vashers 32 andV 33 are placed between the circular saw 24and the bearings 19 and 20, and a washer 34 is placed between the sleeve30 and the nut 31. The bearing 19 has thereon a projection 35 providedwith an opening in which is adjustably ittedfthe oEset stem 36 which isprovided at the inner end of the thrust finger 25 and is locked in `theadjusted position by the set screw 37.

The thrust finger 25 has an outward inclination-toward the circular saw24 and it has its outer edge 38 beveled and normally spaced slightlyfrom the outer edge portion 39 of the circular saw 24.

As shown in this instance the shaft 27 is driven by the sprocket chain40 which is in contact with the sprocket pinion 28 and the sprocketpinion 41 which latter is suitably mounted on one end of the arm 42which has its other end pivotally mountedV at the upper end of theextension 16. The arm 42 normally bears against the stop 43.

The shoe holding device consists of the plates 44 and 45 which areformed and arranged to provide arecess which is inclined forwardly andupwardly and adapted to receive the heel 46 o1" a shoe 47; said plates44and 45 having beveled edges 48 and 49 which are adapted to fit in thecrease between the heel seat and the heel of the shoe. The bevswiss ofthis 11a-tent may be obtained ter eled edge 48 lits in the creaselaround the rear end part of the heel 46 and at the forward end of oneside of the heel, and the beveled edge 49 lits in the crease lat theforward vpart of the other side of the heel. 'Ihe plate 44 is suitablyattached to the upright extension 50 011 One end of the table 51 whichhas a handle 52 at its other end, and the plate 45 is suitably attachedto the lever 53 which has handle 54 at its upper end and has its lowerend mounted on the pivot 55 on the upright eX- tension 50 of the .table51.

In order to adjust the heel holding device relatively to the circular'saw 24, the table 51is pivotally mounted on the arm 56 which :has ahandle 57 at its forward end and has its rear end pivotally mounted onthe frame 11. The table 51 extends substantially at a right angle to the.circular saw 24, and the arm 56 is disposed substantially parallel tosaid circular saw. A .pivot 5S passes through vthe table 51 and the arm56, and said pivot passes through a spring 59 which 'is interposedbetween lthe arm 56 and a nut 60 on the pivot so that the table 51 makesclosecontact with the arm 56. The table 51 is .provided On its undersidewith teeth 6l which are adapted to lit in the notches 62 yprovided inthe lupper part of the arm 56 to positively hold the table 51 inadjusted posi- .tion when it is turned on the pivot 58. pivot 63 passesthrough the rear part of the arm 56 and the part 17 of the frame 11, andsaid pivot passes through a spring 64 which is interposed between thepart 17 and a nut y65 on the pivot so that lthe `arm 56 is held in closecontact with the part 17, The-teeth 66 on the part 17 are adapted to fitin the notches .67 in the underside of the arm 56 to positively hold thea-rm 5.6 in adjusted position when it isyturned on the pivot 63.

From the foregoing, the construction, manner of use, and the advantagesof the improved heel cutting apparatus will be understood by thoseskilled in the art. The shoe 47 is placed to have the beveled edge 48disposed in the crease between the heel seat and the heel 46, and thenthe lever 53 is moved to have the beveled edge -49 disposed in thecrease and hold the shoe so that a part of `the heel can be .cut off.yIt will be seen that the form and arrangement of the plates 44 and 45permit the operator to easily and yquickly place the shoe-and clamp itin the holder. The arm 56 can be turned toward the circular saw 24according to the amount that it is desired to cut off of the heel; andthen the table 51 can be turned to adjust the shoe holding device sothat either a straight .cut or an angular cut longitudinally of the-heel can be made asniay be desired. .In-order to doeffective work incutting the leather and nails of the heel 46, the circular saw 24 mustbe comparatively thin. When a comparatively thin circular saw is used tocut the heel it does not cut in a straight line because the intact part68 ofthe heel 46 presents a greater pressure or thrust against thecircular saw 24 than does the slice 69 which is being cut oif of theheel. The finger2'5 prevents the circular saw 24 from being thrust awayfrom the intact part 68 and causes the circular saw 24 to make astraight out through the Aheel 46.

The construction which has been particularly illustrated and describedadmits of minor changes and, n1odilications-wherefore the right isreserved to all such changes and modifications asV do not depart fromthe spirit and scope of the invention which is defined in the appendedclaims.

I claim: Y
